Hall mobilities and sheet carrier densities in a single LiNbO conductive ferroelectric domain wall
Henrik Beccard, Elke Beyreuther, Benjamin Kirbus +3
For the last decade, conductive domain walls (CDWs) in single crystals of the uniaxial model ferroelectric lithium niobate (LiNbO, LNO) have shown to reach resistances more tha…
R2D2 -- An equivalent-circuit model that quantitatively describes domain wall conductivity in ferroelectric LiNbO
Manuel Zahn, Elke Beyreuther, Iuliia Kiseleva +7
Ferroelectric domain wall (DW) conductivity (DWC) can be attributed to two separate mechanisms: (a) the injection/ejection of charge carriers across the Schottky barrier formed at…
Comparing Transmission- and Epi-BCARS: A Transnational Round Robin on Solid State Materials
Franz Hempel, Federico Vernuccio, Lukas König +5
Broadband coherent anti-Stokes Raman scattering (BCARS) is an advanced Raman spectroscopy method that combines the spectral sensitivity of spontaneous Raman scattering (SR) with th…
Vibrational properties of LiNbO and LiTaO under uniaxial stress
Ekta Singh, Mike N. Pionteck, Sven Reitzig +4
Structural strain severely impacts material properties such as the linear and non-linear optical response. Moreover, strain plays a key role, e.g., in the physics of ferroelectrics…
Impact of 3D curvature on the polarization orientation in non-Ising domain walls
Ulises Acevedo-Salas, Boris Croes, Yide Zhang +11
Ferroelectric domain boundaries are quasi-two-dimensional functional interfaces with high prospects for nanoelectronic applications. Despite their reduced dimensionality, they can…
Tuning the domain wall conductivity in bulk lithium niobate by uniaxial stress
Ekta Singh, Henrik Beccard, Zeeshan H. Amber +4
Conductive domain walls (CDWs) in insulating ferroelectrics have recently attracted considerable attention due to their unique topological, optical, and electronic properties, and…
